That is marvelous practically against a global worming.When we grow trees, we can face it successfully.........................Chamika

that's just partially correct. trees get "satiated" in too high co2 concentration eventually.

greenhouse farmers cAn tell you there is an optimum (about 0.5%) and not a maximum (IMG:style_emoticons/default/wink.gif) but that counts only for trees ... air with 0.5% co2 is not what we would call "fresh" anymore

The effects of climate change are very alarming. The national academy of Sciences has state in unequivocal terms that the effects are substantial and, to quote a report, the result of human activity. Human being is in danger .

Well I will reply with a question, why is this in Group sub forum, and not in Lounge?

Second well global warming is saving us for now, but will kill us soon. Because we should all ready be in new Ice age, but global worming prevented that, the only problem will be when the world goes back closer to sun.

So we should prevent it, but how?

Well each individual can do something, like if you drive car, by checking your pressure regularly in your tires, you will reduce global worming and save gas....there is a lot of things like this, small thing that can make very big difference.

Like in my country, in average every individual in Croatia produces about 6 tons of bad gases which help global warming, so we have this camping to reduce this by 1 ton...it is a good program....

no global worning , is big problem than ice age ...ice age is just an imagination ......guys...!!! and global warning is happening now ....!
